Astigmatism can lead to reduced vision, but blindness is not a risk. However, it may be difficult for people with astigmatism to read and write without glasses or contacts because of the blurriness in the distance.
Many people who have mild astigmatism may not even realize it. People who have more severe astigmatism can have symptoms that include blurred vision, eye discomfort, squinting, and headaches.
But without treatment, astigmatism can: impact a child's performance in school and sports. lead to amblyopia (lazy eye) and vision loss.
Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause blindness.
As mentioned above, if an eye injury or eye surgery caused you to develop astigmatism that cannot be corrected, you may be entitled to VA disability compensation.
Severe astigmatism can cause serious symptoms that affect daily functioning. Blurred vision from severe astigmatism can cause headaches that impact your health.
Between . 75 and 2 diopters is considered mild astigmatism. Between 2 and 4 diopters is moderate astigmatism, and 4 or more diopters is considered significant or “bad” astigmatism. Generally, eyes with 1.5 diopters of astigmatism or more require correction.
While astigmatism cannot be cured, glasses and contact lenses can be used to treat the blurry vision that results from having astigmatism. For those wishing for a more permanent solution to blurry vision, refractive surgery is required.
Prescription eyeglasses for astigmatism are generally considered optional if your uncorrected vision (meaning your vision without corrective lenses) is 20/40 or better. However, even if your vision is 20/40 or better, you might still end up with eye strain or headaches if you don't wear glasses.
Either type of astigmatism can cause blurred vision. Blurred vision may occur more in one direction: horizontally, vertically or diagonally. Astigmatism may be present from birth, or it may develop after an eye injury, disease or surgery.
Blurred vision is the most common astigmatism symptom. It also makes it hard to see details on objects, like the words printed on a menu in front of you, or letters on a road sign in the distance. Other astigmatism symptoms include: Seeing a glare or halos around lights.
Like eyeglasses, contact lenses can correct most astigmatism. They are available in a variety of types and styles. Contact lenses are also used in a procedure called orthokeratology. In orthokeratology, rigid contact lenses are worn during the night while sleeping until the curvature of the eye evens out.
High amounts of astigmatism can be corrected with LASIK, though this increases the likelihood a follow-up LASIK enhancement may be needed to fine-tune the correction. LASIK for astigmatism is an excellent option when compared to other alternatives like eyeglasses or contact lenses.
In the beginning, eyeglasses can typically return a patient's vision back to 20/20. However, more severe astigmatism may require surgical interventions. Also, astigmatism often becomes more severe with age, so most patients require stronger and stronger lens prescriptions as they get older.
For people with astigmatism, who require toric lenses, the maximum is about -9 Dioptres of sphere. These are also available from Pure Vision 2 HD Astigmatism, and Biofinity Toric.
Astigmatism is linked to genetics

The result is blurry vision. People with astigmatism may experience mild to severe distorted vision, depending on the degree of astigmatism. While myopia (nearsightedness) makes far-away objects blurry and hyperopia (farsightedness) makes close-up objects blurry, astigmatism makes things blurry at every distance.
There are three options to correct astigmatism – glasses, contact lenses or laser eye surgery. Prescription glasses or contact lenses can correct astigmatism (along with long-sightedness or short-sightedness, if necessary). Alternatively, laser eye surgery can correct astigmatism and give you clearer vision.
Astigmatism is measured in diopters. A perfect eye with no astigmatism has 0 diopters. Most people have between 0.5 to 0.75 diopters of astigmatism. People with a measurement of 1.5 or more typically need contacts or eyeglasses to have clear vision.
Astigmatism is a common and treatable condition that prevents light from going into your retina properly. It causes bright visual distortions that look like halos, streaks, and starbursts. Driving at night with untreated astigmatism can be difficult and even dangerous.
Astigmatism worsens depth perception of the eye since it blurs the edges and outlines of everything you see. You may notice you feel unbalanced and that it is difficult to distinguish how far away objects appear – this could affect the overall quality of your vision.
AXIS refers to the angle of the astigmatism in your eye and has nothing to do with the severity of your prescription. These digits can be anywhere between 0 and 180 degrees such as 020, 090, 120 or 170 etc. In some instances, your optometrist may have written your CYL and AXIS freehand which can be separated by an “X”.
Is astigmatism 180 axis bad? An axis of 180 degrees means that the astigmatism is horizontal. Hence, the patient is moderately near-sighted with a slight degree of horizontal astigmatism.
